rIhe locking device of the`present invention, while capable of a Wide field of utility, is peculiarly adapted for use in connection with the doors of a closed automotive vehicle, l

y An object of the invention is to provide a locking device of this` character which operates by a direct thrus on a handle member as opposed toMthe usual method ofv Aprovide la locking device which will be simf ple and practicallin construction, rugged, durable and efli'cient in use, which is capable of ready installation upon all standard makes of automobiles, and which lends itself 'to economical manufacture. c

f With the above noted and other objects 1n view, the invention consists in certain novel features of; construction` and combinations and arrangements of parts, as will be more fully hereinafter set forth and pointed out in the claims. The .invention may be more fully understood from the following` de'- scription in connection with:I the accompanying drawings, wherein-.-

Fig. 1 is a view in side elevation of an f' ,automobile showing my improved lock ap,-

plied to the doors thereof.

Fig. 2 is a transverse sectional view through a door and frame, showing the lock in applied position.

Fig. 3 isa vertical sectional view onv thev line 3,-3 of Fig. 1.

Fig. 4 is a sectional view on the linev 4-4 r'of Fig. 3 illustrating a slight modification.

I have used reference character 10'to indicate a closed automotive vehicle includ.- ing doors 11. These doors are hinged as at 12 to theV body of the car, and mountr` glass panels' 13 for manually controlled vertical sliding movement as is customary in automobile construction. At the outer edge" of the door. there is provided a bolt member 14 adapted to enter a keeper 15 in the door `:frame or car body to lock the .I door against swinging movement,

My` 'nvention is particularlI concerned V14 and its with the construction of the bo associated operating mechanism. It will be noted fromFigs. 2 and 3 that the bolt is guided for movement in a horizontal plane between upper and lower guide ways 16,

and held againstlateral play by vertical guide ways 17. The bolt is of skeleton formation, including a relatively large central opening 18. A spring-19 mounted in. l

the opening and bearing against a hollow guide way 20 for the shank 21, tends to urge the bolt outwardly, and retain its outer end within the keeper 15.

Near the other end ofthe opening' 18 in the bolt, I mount'a roller 22 on a cross pin 23. This roller coacts with a cam notch 24 in the shank 21 to elect retraction ofthe bolt when a direct thrust is imparted to the shank to l eifect axial movement of the latter. Operats"ing knobs 25 are mounted on opposite ends of the shank 21. To gain entrance to the car, the outer knob 25 is pulled, shifting the flo .gain egress from the car,- the inner knob is pushed, axially shifting` the shank and retracting the bolt. It -is desirable to provide 'some means which 'will prevent. accidental opening of the door from the inside,

shank outwardly and retracting the bolt.l l

such as might. be caused by a passenger 'leaning against kthe inner knob, or being thrown against said knob as the car rounds a corner.y Various means might beJ utilized to perform this safe-guarding function. I have shown one means which consstsof a semi-cylindrical member 26 secured tothe inner face of the door about the knob 25. and vformed with an inwardlyturnedvflange 27 partially covering the knob and preventing operation thereofv by a person leaning l against it.

If desired I may` provide some supplemental'means for retracting the -bolt,'said means bein entirely independent of the two knobs. I ave shown such supplemental .means ascon'sisting of a link 30 guided-in bearingbrackets 31 within the'hollowdoor The link is secured to the rear end of th bolt as by'ajpin or screw 32, land terminates in an off-set handle member 33 working in a slot 34 formed at the inside of the door near its pivoted edge. This construction permits one of two operating mechanisms to be used for opening the door .from

vthe inside. At least one of them will always be iny convenient position for manual operation by an occupant of the machine.

If it is desired to lock the door from the .7. outside, any suitable locking mechanism be employed yfor retaining the bolt against ma'lly spring pressed outwardly, a shank may retraction. In Fig. 2 I have shown such means which includes a set of key operated tumblers 35, "coacting with a stud member 36 on the rear end Iof the bolt. This stud member may conveniently form an extension of the retaining pin or screw 32. Obviously many forms of lookin means might beremployed, and any stan ard lock mounted in the usual manner on the outside of the door.

Asa generalrule only one outside lock is used, the remaining doors being locked on the inside before the occupant, leaves the car. I have shown oneform of such interior locking mechanism in' Fig. 4, said mechanism including a lever 40 fulcrumed on a in 41 carried by the guard member 26. The ver is formed with a tail portion 42 workingthrough a slot 43 in the member 26 to effectively block outward movement of the knob 25.

IIt is to be understood that various other means Jmight be utilized for locking the doors from the inside, and 'that while the embodiment of the invention is a preferred one, it will be evident that various changes and alterations might be made in the general y form and arrangement of parts described,

without 'departing `from the invention.

Hence I- do not` wish to limit myself to theY details set forth, but .shall considermyself at liberty. to make such changes and altera-A tions as fairly fall -within the spirit and scope ofthe appended claims.

Iclaim f l i A I".

1Q yIn an automobile door lock, a bolt norextending transversely through the door and carrying handles on each end, means whereby a direct thrust on the inside handle effects retraction of the bolt, and means protecting said handle against accidental operation, said protecting'means including 1 the dir-et thrust of a pushing instrumentality of the same size as the knob.

j 2. In an automobile door lock, a` bolt normally spring pressed outwardly, a shank extending transversely through the door handles of each end ofV the shank, means whereby a direct thrust on the inside' handie effects retraction of the bolt, and an a proximately semi-cylindrical protective Is ell fixed to the inslde of the door and encircling the handle to prevent accidental retraction of the bolt, and means associated with the shell for locking the shank against movement.' 3.v A device of the class ,described in claim 2, 'wherein said means includes a latch mounted on the shell, and adapted to extend iiltthe path of the operatlng handle to block movement thereof to bolt retracting position. y MINNIE D.
